(2) Baud rate error during transmission
(Target Baud Rate)
UART Baud Rate
The baud rate error of UART (UART0, UART1) communication during transmission can be calculated by the
following expression. Make sure that the baud rate at the transmission side is within the permissible baud rate
range at the reception side.
Here is an example of setting a UART baud rate at f
(Baud rate error) = (Calculated baud rate value) ÷ (Target baud rate) × 100 − 100 [%]
This does not include the error related to the oscillation accuracy of the X1 oscillator and internal high-speed
oscillator.
